I am packaging a binary package that has been built with the SDK created

During do_package I am getting an error that a dependency on
libGLESv2.so()(64bit) cannot be met. Adding mesa to RDEPENDS does not
resolve the issue. I can bypass it in the recipe by adding file-rdeps to
INSANE_SKIP. However, then when the rootfs is created libdnf complains
that the dependency on libGLES is not met and aborts.
The application works just fine on the target if I copy it manually to
the rootfs but that's not the best thing to do. It should be packaged
and installed.
Unfortunately I don't understand well enough how these checks work and
why they are complaining about it. Maybe somebody can shed some light on
it.
Bitbake versions its shared libraries. So a binary built by Bitbake will
link against libGLESv2.so.1.3 (or whatever the version of the lib
actually is).
This also means that the only shared library that can be used for
linking is the versioned one.
Bitbake reads the NEEDED section from objdump to identify the runtime
dependencies and automatically add the packages providing those
libraries to your image. This is the reason why you do not need to
explicit RDEPENDS for packages created by recipes in DEPENDS.
The issue here is that Bitbake creates a package which provides
libGLESv2.so.1.3 but your binary requires libGLESv2.so and Bitbake
cannot find a package for it.
Usually the way to do it is to ignore the warning like you did, or build
the binary in Yocto directly. I assume the latter is not possible
because it is proprietary software compiled by a third-party and you
don't have access to the source code.
As to how to fix this issue with dnf, I do not know.
One possibility could be to patchelf your binary in Yocto directly but
you'll need to update this patchelf line every time you update libGLESv2
version because it is not possible to get the version from one recipe in
another.
Cheers,
Quentin
